EDVARD L. HILDERIBRAND, OF SULLIVAN, INDIANA.

AXLE-SPINDLE'.

SPECIFICATION forming' part of Letters Application iiled March 11,1899.

To all whom t may conccrnf Be it known that I, EDWARD L. HILDER- BRAND, a citizen of the United States, residing at Sullivan, in the county of Sullivan and State of Ind iana, have invented a new and useful Axle-Spindle, of which the following is a specification. l 4 This invention relates to axle-spindles, and has for its object to provide a removable skein with means for lubricating the inner end of the axle-box.

With this end inview the present invention consists in the combination and arrangement ot' parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claim. i

In the drawings, Figure 1- is a horizontal longitudinal sectional view showing the im provements applied to an axle. Fig. 2 is a transverse sectional View on thelinexw, Fig. 1. Fig. 3 is a detail perspective View ot' the axle-skein.

Corresponding` parts are designated by like reference characters in all the figures ot the drawings.

Referring to the accompanying drawings, 1 designates an ordinary spindle having the usual threaded outer extremity 2 and also threaded at its inner end, as at 3.

The skein 4, which is illustrated in detail in Fig. 3, is internally threaded, as at 5, at its inner end. This latter end is enlarged and provided with an annular flange 6, which overhangs the body of the skein and forms therewith an annular groove orpocket 7, surrounding the exterior of the threaded endof the skein. Extending longitudinally ot' the upper face of the skein is a groove 8, forming an oil chamber or reservoir, and branch grooves 9 extend out from opposite sides of the reservoir. The branch grooves 10 at the iianged end ofthe skein extend into the pocket 7 to convey the lubricant into the same.

By reference to Fig. 1 particularly it will be seen that the skein is removably fitted to the spindle byrneans of the threaded connections 5 and 3,respectively. A suitable washer 11 is placed in the pocket 7 of the skein, and the axle-box 12 is then slipped upon the skein. The inner end 13 of the box is fitted into the pocket 7, a washerlt having been Patent NO. 624,805, dated May 9, 1899.

previously fitted. to the end ot the box against the annular shoulder 15. The outer threaded end of the spindle is provided with the usual hub-attaching nut 16. The groove 8 being in the top of the skein, which is fixed upon the spindle,a suitable lubricant is placed in the groove, and as the box is fixed to the hub by means ot' the wings 17 in the common manner the box turns upon the skein and the lubricant is fedautomatically through the branch grooves 9 to the interior of the box. The' branch grooves 10 lead into the pocket 7, and thereby convey the lubricant to the inner end of the axle-box, which turns within the pocket.

The present construction provides an ex ceedingly simple and efficient device, as the skein can be readily replaced when worn and the lubricant is fed directly to the parts needing the same. The fiange 6, overhanging the inner end of the box and abutting against the shoulder of the same, prevents sand and dirt from having access to the bearing-surface of the box and skein.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claim maybe resorted to without departing from the spirit or sacrificing any of the advantages ot this invention.

Having thus described the invention, what is claimed is The combination with an axlespindle, of a'skein having an exterior annular flange .at

its inner end overhanging the body of the` skein and forming therewith an exterior pocket, the upper exterior face of the skein having an oil-chamber-provided therein and branch grooves leading therefrom, some of the grooves leading into the annular pocket, and an axle-box having its inner end seated within the Aannular pocket of the skein, the grooves leading into the pocket forming means whereby the inner end of the box may be lubricated, substantially as shown and described. f

In testimony that I claim the foregoing as my own I have hereto 'affixed my signature in the presence of two witnesses.
